Injectors briefly shutting off
Hello everyone,
Wondering if anyone could provide some insight, under full throttle I noticed in my datalog that I was getting some knock, dug a bit deeper and noticed that for a brief moment both my port and direct injectors stop injecting fuel completely. I think this only happens occasionally I'll try and see if I can repeat it. And it only seems to happen for a very short period of time, I don't even notice it when I'm driving. I have attached an image of the datalog and highlighted where this issue occurs. Some details on the car gtx3076r, dw700 injectors, ecutek racerom, rom version B01C Thanks in advance! |

Check all of your safety parameters , make sure there's no custom load, boost limit, traction, oil temp or other things using fuel cut as the reduction method.
If it's only happening at full throttle and boost, you're likely hitting a limiter of some sort (check load limiter as well). I don't see why anything would ever command fuel to stop rather than changing throttle opening, retarding ignition timing or wastegate duty so it's either erroneous or someone did something stupid. Trust but verify!

Thanks for the suggestion. This made me think that I may have tripped traction control, I floored it making a left turn.
